All triangles are 3-sided. There are 3 different kinds. One where all 3 sides are equal length and have equal angles is called an Equilateral triangle. A triangle with two sides and angles the same is known as an Isosceles triangle. The last kind of triangle has 3 unequal sides and 3 unequal angles and it is called a Scalene triangle.
Triangles.
All triangles have three sides
All triangles have three vertices.
Impossible shapes. They are four sided shapes with three sides!
A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.
Triangles.
Because there are 540 interior degrees in a five sided figure and the total sum of three triangles is 540 degrees
All triangles have three sides
Impossible shapes. They are four sided shapes with three sides!
All triangles have three vertices.
Such a three sided triangle with two right angles is impossible.
A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.
there are 15 triangles in a 17 sided polygon
There are 17 triangles in a 19 sided polygon
yes... because tri- means three, angle-means sides.
Equilateral, Isosceles and Scalene.
